The new oldtest directory is in test/old/testdir. The reason for this is that many tests have hardcoded the parent directory name to be 'testdir'.

This directory contains tests for various Vim features.
|
|
For testing an indent script see runtime/indent/testdir/README.txt.
|
|
|
|
If it makes sense, add a new test method to an already existing file. You may
|
|
want to separate it from other tests with comment lines.
|
|
|
|
TO ADD A NEW STYLE TEST:
|
|
|
|
1) Create a test_<subject>.vim file.
|
|
2) Add test_<subject>.res to NEW_TESTS_RES in Make_all.mak in alphabetical
|
|
order.
|
|
3) Also add an entry "test_<subject>" to NEW_TESTS in Make_all.mak.
|
|
4) Use make test_<subject> to run a single test.
|
|
|
|
At 2), instead of running the test separately, it can be included in
|
|
"test_alot". Do this for quick tests without side effects. The test runs a
|
|
bit faster, because Vim doesn't have to be started, one Vim instance runs many
|
|
tests.
|
|
|
|
At 4), to run a test in GUI, add "GUI_FLAG=-g" to the make command.
|
|
|
|
|
|
What you can use (see test_assert.vim for an example):
|
|
|
|
- Call assert_equal(), assert_true(), assert_false(), etc.
|
|
|
|
- Use assert_fails() to check for expected errors.
|
|
|
|
- Use try/catch to avoid an exception aborts the test.
|
|
|
|
- Use test_alloc_fail() to have memory allocation fail. This makes it possible
|
|
to check memory allocation failures are handled gracefully. You need to
|
|
change the source code to add an ID to the allocation. Add a new one to
|
|
alloc_id_T, before aid_last.
|
|
|
|
- Use test_override() to make Vim behave differently, e.g. if char_avail()
|
|
must return FALSE for a while. E.g. to trigger the CursorMovedI autocommand
|
|
event. See test_cursor_func.vim for an example.
|
|
|
|
- If the bug that is being tested isn't fixed yet, you can throw an exception
|
|
with "Skipped" so that it's clear this still needs work. E.g.: throw
|
|
"Skipped: Bug with <c-e> and popupmenu not fixed yet"
|
|
|
|
- The following environment variables are recognized and can be set to
|
|
influence the behavior of the test suite (see runtest.vim for details)
|
|
|
|
- $TEST_MAY_FAIL=Test_channel_one - ignore those failing tests
|
|
- $TEST_FILTER=Test_channel - only run test that match this pattern
|
|
- $TEST_SKIP_PAT=Test_channel - skip tests that match this pattern
|
|
- $TEST_NO_RETRY=yes - do not try to re-run failing tests
|
|
You can also set them in Vim:
|
|
:let $TEST_MAY_FAIL = 'Test_channel_one'
|
|
:let $TEST_FILTER = '_set_mode'
|
|
:let $TEST_SKIP_PAT = 'Test_loop_forever'
|
|
:let $TEST_NO_RETRY = 'yes'
|
|
Use an empty string to revert, e.g.:
|
|
:let $TEST_FILTER = ''
|
|
|
|
- See the start of runtest.vim for more help.
|
|
|
|
|
|
TO ADD A SCREEN DUMP TEST:
|
|
|
|
Mostly the same as writing a new style test. Additionally, see help on
|
|
"terminal-dumptest". Put the reference dump in "dumps/Test_func_name.dump".
|
|
|
|
|
|
OLD STYLE TESTS:
|
|
|
|
There are a few tests that are used when Vim was built without the +eval
|
|
feature. These cannot use the "assert" functions, therefore they consist of a
|
|
.in file that contains Normal mode commands between STARTTEST and ENDTEST.
|
|
They modify the file and the result gets written in the test.out file. This
|
|
is then compared with the .ok file. If they are equal the test passed. If
|
|
they differ the test failed.
|
|
|
|
|
|
RUNNING THE TESTS:
|
|
|
|
To run a single test from the src directory:
|
|
|
|
$ make test_<name>
|
|
|
|
The below commands should be run from the src/testdir directory.
|
|
|
|
To run a single test:
|
|
|
|
$ make test_<name>.res
|
|
|
|
The file 'messages' contains the messages generated by the test script. If a
|
|
test fails, then the test.log file contains the error messages. If all the
|
|
tests are successful, then this file will be an empty file.
|
|
|
|
- To run a single test function from a test script:
|
|
|
|
$ ../vim -u NONE -S runtest.vim <test_file>.vim <function_name>
|
|
|
|
- To execute only specific test functions, add a second argument:
|
|
|
|
$ ../vim -u NONE -S runtest.vim test_channel.vim open_delay
|
|
|
|
|
|
- To run all the tests:
|
|
|
|
$ make
|
|
|
|
- To run the test on MS-Windows using the MSVC nmake:
|
|
|
|
> nmake -f Make_dos.mak
|
|
|
|
- To run the tests with GUI Vim:
|
|
|
|
$ make GUI_FLAG=-g
|
|
|
|
or
|
|
|
|
$ make VIMPROG=../gvim
|
|
|
|
- To cleanup the temporary files after running the tests:
|
|
|
|
$ make clean
|
